A Kosha (also Kosa; Sanskrit कोश, IAST: kośa), usually rendered "sheath", is a covering of the Atman, or Self according to Vedantic philosophy. There are five Koshas, and they are often visualised as the layers of an onion.
The koshas are energetic layers or sheaths that move from the outermost layer of skin to the deep spiritual core. The koshas provide a framework for conceptualizing ourselves. Much like the chakra system, the kosha layers come packaged with their own individual physiological function and psychology. In some respects, the kosha layers mirror the psychology of the chakras.
For those of you wondering what the individual koshas are and how they relate your being as a whole, below you'll find brief descriptions of each.
1. Physical body - Annamaya kosha
The first layer of the koshas represents the physical body, including the skin, muscles, connective tissue, fat and bones. When you pinch the side of your waist and feel the skin and muscle under your fingers, you engage with annamaya kosha. For a lot of people the first layer might be where we spend the most time hanging out, locked in our physical senses.
2. Energy body - Pranamaya kosha
The second layer represents the pranic or subtle body — in essence, it's the circulatory system for prana, or “life-force energy.” It also includes the fluid, physical aspects of the anatomical body that control the movement of blood, lymph and cerebrospinal fluid through the body and the circulatory movement of breath through the respiratory system. In psychological terms, pranamaya kosha controls our bodily and spiritual rhythm.
3. Mind body - Manomaya kosha
The third layer takes us into the deep recesses of the mind, emotions and nervous system. While modern science has developed an acute understanding of the inner working of the brain, the mind, motivations and emotions still retain a mysterious quality. The manomaya kosha makes up the control panel for the emotional and physical body, sending messages through your brain synapses and the central nervous system. It’s this layer where you move from physical feeling and rhythm to emotional feeling.
4. Intuitive body - Vijanamaya kosha
Diving underneath the sea of emotions in the manomaya kosha, we reach the wisdom body of the fourth kosha —Vijanamaya. It’s here that we developawareness, insight and consciousness. Emotions left unchecked by awareness are destructive. The awareness of vijanamaya kosha illuminates our deeper desires and motivation and allows us to see the choice we have in all things. Instead of simply feeling or acting, we choose to feel or act with intention. Sometimes the intention is simply to move past the emotion into pure sensation and bliss.
5. State of bliss - Anandamaya kosha
The fifth and last kosha drops from conscious awareness into the pure and radiant bliss body. Within the anadamaya kosha, you might experience connection with all things, liberation from suffering and a state of being often described as “in the flow.”
